    I have the Amp+ installed on my Rpi2, and have configured the HiFiBerry setting appropriately. I have connected my speaker wires to the the four speaker binding posts per this diagram:
    I opened YMPD and chose a radio station at random. The blue bar progresses but no sound. I plugged in a USB stick with some music files on it. Stick mounted ok, appeared in “Browse DB” in YMPD, but when selected, appears to play, but again no sound.
    Tested speakers with low-power 1v battery and they are working ok.
    What am I missing?

    Hi Hilary,
    I just tested the MPD player myself to make sure there are no new errors in our newest version of Max2Play. However, I could, unfortunately, not replicate your issue.
    What parameters are displayed in the “Soundcard Settings”? There should be a selection in the “Sound Device” line indicating the hifiberry amp.
    What power supply are you using? The Amp’s need a separate power supply since they power passive speakers, the Amp itself and the Pi (no normal Pi power supply should be connected).

    14. November 2016 at 21:49 #23908

    Hi Heiner,
    The power supply is the same as the one recommended:
    60 W Watt, Single Output, 18 [email protected] A External Power Supply Desktop AC-DC Power Supply
    Under Raspberry Pi Settings, Soundcard Setting is Hifi Berry Amp/Amp+
    However, under MPD Music Player Soundcard Settings, sysdefault was bcm-something, so I changed it to
    sysdefault – snd_rpi_hifiberry_amp
    and now it’s playing!
    Wow, I thought I’d done all that, but maybe I didn’t save it.
    Now the problem is too much sound!
    Next question: I have no control over the volume and it’s blasting the neighbors! The volume setting in YMPD doesn’t change the volume at all. What do I do to adjust volume?
    Next question: How do I add my local radio stations to the choices for Radio?


    15. November 2016 at 16:20 #23912

    Hi Hilary,
    For volume control, please add the parameter “hw:0” in the option “mixer device”. If this does not work, please change it to “hw:1”. This connect your volume control of YMPD to the Amp’s.
    You can add radio stations by adding the file linking the station to the MPD folder. However, if you are looking for a simpler interface that has most radio stations preloaded and the ability to add stations in its own web interface, try out Squeezelite in combination with the Squeezebox Server. Just install the Server with one click (select 7.9 nightly) and activate Squeezelite with the sysdefault hifiberry amp option selected (make sure MPD is not running anymore). Then, you can control the playback, volume, etc. via the Squeezebox Server web interface or with one of the great Apps for Android (Squeezer) or iOS (iPeng).

    Hi Hilary,

    please choose “Master” as mpd mixer control in the MPD settings.


    15. November 2016 at 22:46 #23919

    Hi Heiner,
    It was set to hw:0 so I changed it to hw:1. Even with a “Save” it didn’t work until I rebooted. I think it should be made clear somewhere that rebooting is necessary after making changes on the MPD page.

    Re: “adding the file linking the station to the MPD folder” — can you give me more of a step-by-step for that? Firstly what file? where do I get it? Secondly what MPD folder, and how do I access it? (Is this in the GUI or by Putty?)
    Perhaps an example would help: I want to add this radio station — https://kpfa.org/

    Hi Stefan,
    Thanks for the additional info.

    Hi Hilary,
    You can add a file in the format of .pls or .m3u including your desired radio stations. You can do this by adding a share for the MPD player, the path is named in the MPD’s advanced options as well as information on how to add the music or in this case the radio stations playlist file and you can find out how to mount a samba share with our help section on the right in the GUI of the Filesystem Mount plugin.

    19. November 2016 at 17:53 #24024

    Hi Heiner,
    I added the share following these instructions:

    The radio station’s playlist file is this:
    So I created a text file with these 5 lines:

    And put it in the RADIO folder.
    It appears in the database but doesn’t play. Please advise.


    21. November 2016 at 8:02 #24038

    Hi Heiner,
    OK, I think I got the radio station thing working now. I didn’t realize I could download that m3u file.

    Now I have another issue. I want to add a Network Path to the Music folder on my Windows desktop. I found the folder using “Show Network Devices”.
    I added this:
    //HILARY7/Music /mnt/share cifs user=Hilary,password=***,sec=ntlm,iocharset=utf8
    It mounted successfully.
    However, I don’t see it in the YMPD database.
    What next?


    23. November 2016 at 16:41 #24130

    Hi Hilary,
    Please have a look at the basic settings of the MPD in our web interface. There you will find info on the music folder and its mount options:
    To access your music on a network share, you have to setup the share with the mountpoint folder /mnt/mpd.

    24. November 2016 at 6:31 #24157

    Hi Heiner,
    So you mean this:
    //HILARY7/Music /mnt/share cifs user=Hilary,password=***,sec=ntlm,iocharset=utf8
    should be this:
    //HILARY7/Music /mnt/mpd cifs user=Hilary,password=***,sec=ntlm,iocharset=utf8

    Now I see the shared folder under “MOUNT” — thanks!
    I think the instructions could be clearer, with examples.


    24. November 2016 at 15:13 #24162

    Thank you for the feedback, we will look into making the documentation more transparent and understandable. Good to hear it all worked out!

    1. December 2016 at 7:32 #24427

    Hi Heiner,
    It worked out only temporarily unfortunately. The contents of the /mnt/mpd folder disappeared quite soon after they appeared. And they stayed disappeared for several days, even with rebooting the Pi and desktop and router. Then yesterday they appeared again and I was able to play some of the tracks. But now gone again. The radio playing was also on/off — sometimes just stopping for no apparent reason after playing for an hour or more.

    So I decided to try your suggestion of the Squeezebox Server:
    “Just install the Server with one click (select 7.9 nightly) and activate Squeezelite with the sysdefault hifiberry amp option selected (make sure MPD is not running anymore). Then, you can control the playback, volume, etc. via the Squeezebox Server web interface or with one of the great Apps for Android (Squeezer) or iOS (iPeng).”
    You didn’t say how to activate Squeezelite, but I found it in the Audioplayer. I have turned off the MPD player and ympd. Now one of my radio stations appears to be playing — I see it in the Logitech Media Player, and in the Squeeze App on my phone. But no sound once more! Is there another setting somewhere that I have missed?


    1. December 2016 at 12:12 #24429

    Please check whether your sound card selection is correct (should include hifiberry amp in the name) and whether the MPD still has autostart activated, if so, deactivate.

    1. December 2016 at 21:41 #24476

    The soundcard selection in Squeezelite is sysdefault – snd_rpi_hifiberry_amp
    MPD does not have autostart activated. The only autostart is Squeezelite.
    What should I do next?

    2. December 2016 at 5:07 #24478

    Still no sounds, so I decided to go back to MPD. I unchecked autostart on Squeezelite, rebooted, and tried to start MPD Player and got this error message:

    Trying to launch … NOT successful Click here to show detailed information
    /etc/init.d/mpd: 57: /etc/init.d/mpd: log_daemon_msg: not found

    (Click here doesn’t open a page or any additional information)
    I am not running Kodi.
    Do I have to remove Squeezebox Server?
